Global warming.

Global warming is back on earth:-
 
The greatest fair is that looms over the world today is global warming. Every year the average temperature of the earth is increasing by a small margin. It is enough to cause havoc to our planet. This is caused mostly by the green-house effect. As a result the glaciers of the world are meal ting rapidly and the ice of the Antarctic is also meal -ting fast. The level of water has already risen by several meters. This is a great danger as many islands and costal regions are expected to be erased from the map. People from all over the world urgently need to take all possible measures to prevent Global warming. Massive tree plantation and reduction in the emission of harmful gases like carbon dioxide is must. Only them humanbelings can survive on earth for a longer period of time.
